E90 spare tire kit

Hi, I remember reading about a spare tire kit for E90's in one of the Roundel magazines. I have lost the article and I can't find it in the archive here. If anybody remembers the name or the link where it can be found, please post it here. It would be greatly appreciated. I'm currently looking for an '07, 328XI CPO and the first thing I will do is replace the tires to quieter, standard tires since I don't think the technology nobody asked for is better than the standard tires.

So far I have owned a '94, E36, and a '02, E46, and I can't wait to get my hands on the E90, as soon as I find an Arctic metallic one.
